Alrighty then, after heavy debugging and researching, I've finally found the cause (+ Solution) for the 301 errors:

Cause:

Long story short: Unreal Engine doesn't support HTTPS, and we are stuck with

- HTTP External HyperLinks
- HTTP Hosts >>>ONLY<<<

Solution:

- Host your NewsSource yourself, in any web host that:


Error 301 (Permanently Moved) means the host no longer supports http (e.g. Github Gists, PasteBin, Paste.ee blah blah blah etc etc etc...)

All of these hosts no longer support http, and modern browsers automatically refresh the page with https if they receive error 301.

Unreal Engine doesn't support https, thus, you cannot use https and expect it to redirect you to http by itself!

Proof:

- Working in-game as of July, 21, 2021: https://imgur.com/a/NrW0OwK
- Self Host of MOTD.txt: https://imgur.com/wlI9hIV (Status 200 with http)
- Github gists: https://imgur.com/tliTDJm (Internal redirect error), which will always fail to be read by the UE in-game.

I have pushed a refactored version of the NewsFixer (With updated class names, updated config, cleaned up code, indentation blah blah), but I made no release! I want to change a couple more things before making a new release.

You can have a look with the changes here: https://github.com/Bleeding-Action-Man/NewsFixer/tree/refactor-motd-class

Hope this answers your questions, technically.
